Heyaaa! that's odd af, it def has to be how unity webgl works with firefox cause its pretty fine in both opera edge and chrome, thats off, super sorry about that :(
also 100% fair with that, we were wanting to zoom them in your face so anyone could read no matter what, but time got us there aha-
def some bugs were gonna fix there after the jam ends! Also saw you got stuck on some parts
SPOILER:
the 2nd room mainly, that one is more for the "reality" part, the main puzzle is to move and pull the objects around to reflect in the real world, mainly pushing the bed to near the closet, then you can grab a shard, from there move the frog out of the way and go back to the game and that square blocking the block should be gone by then, push the tv on your right, and then place the shard on the empty photo frame, it should then unlock the door at the end of the hall and bam :D
hope this help, I know my other team member Shabrys is making a full playthrough soon to help out as well in case :)
but thanks for playing! really sorry for those bugs, idk why firefox bugging out with it, we'll see what we can do for sure! also make it a bit more readable and easier to grab items you need to read :)
